Written summary
AIKO (Shanghai Aiko Solar Energy Co., Ltd.) was founded in 2009 and is headquartered in Shanghai, operating a vertically integrated manufacturing network across sites such as Yiwu, Foshan, Zhuhai and Jinan, with an R&D hub at Solarlab AIKO Europe in Freiburg, Germany. The company earned BloombergNEF Tier 1 status in Q3 2024 and now runs annual production capacity of roughly 35.5 GW, placing it among the top ten module makers by scale. Seraphim, founded in 2011 and based in Changzhou, Jiangsu, has held BNEF Tier 1 status for eleven consecutive years since 2015 and operates roughly 13 GW of global capacity across six manufacturing bases in China and South Africa - on institutional footprint and current production scale, AIKO is the larger and more recently ascendant of the two.
AIKO's product line is built around its proprietary ABC (All Back Contact) cell technology, which moves all contacts to the rear of the cell to boost active surface area, delivering commercial efficiencies above 24% along with a clean, uniform aesthetic that is particularly well suited to residential rooftop installations, though AIKO also markets ABC modules for commercial and utility-scale use. Seraphim takes a more conventional, diversified approach centered on TOPCon modules (its Sable and Nebula series), supplemented by PERC, HJT and lightweight dual-glass panels, with higher-power variants up to 730 W aimed at commercial and utility-scale projects.
For buyers prioritizing aesthetics and maximum efficiency per square meter on residential or constrained rooftops, AIKO's ABC technology is generally the stronger default choice. For large commercial or ground-mount projects where cost per watt and a long, proven Tier 1 track record matter most, Seraphim remains a dependable and typically more price-competitive alternative, though the gap in headline efficiency between the two brands has narrowed in recent product generations.
